Abstract

Abstract

The bulk density of soil samples obtained with a hydraulic soil coring machine, for both core segments and clods, was compared to the bulk density of soil samples obtained with a Uhland sampler and natural clods taken from a soil pit. Subsurface, upper B, and lower B horizon samples were compared. Clods gave bulk density values that were significantly higher than cores in the upper solum, where small structural units occur; however, in the lower solum, where soil structural units are large or massive, variation between clods and cores was not statistically significant. There was no significant difference in bulk density due to the method of obtaining clods or cores.
